Chapter 195: bronze sword embryo

& lt; remove impurities! Master, what should I do? &"Asked Luo Yu.

&"As a teacher, here is a piece of ordinary material, bronze and iron essence! Try to make a bronze sword with this bronze iron essence. Now I'll teach you how to remove impurities from it.

&"Mm-hmm.

& lt; to cast swords, preheat the melting furnace first & gt; haolao Dao

Luo Yu nodded, raised Lei Yan beast fire in his hand, and put his hand on the wall of the furnace. Lei Yan beast fire was absorbed by the red copper furnace. After the fist size beast fire was inhaled by the red copper furnace, it turned into a raging fire in the furnace with the blessing of the inscription.

This is one of the functions of the melting furnace, which is to strengthen the flame of the fire controller and save energy when melting. Haolao's nine flame is separated from the furnace, and he only needs to control the ordinary weapons with his divine sense, which is very convenient

the preheating of the melting furnace is to prevent the danger of furnace explosion when the temperature rises suddenly.

After the Leiyan beast fire in the real red copper furnace burned for a moment, Hao threw the bronze iron essence into the melting furnace & lt; you first try to find the melting point of the bronze iron essence, and then keep the constant temperature & gt;

& lt; HMM, I know! &Quot;

Luo Yu nodded and practiced the mental method of swallowing and refining the body. He controlled the temperature of Lei Yan beast fire by mobilizing the Lei Yan beast fire in his body. The temperature of Lei Yan beast fire gradually increased, and the Lei Yan beast fire in the melting furnace wrapped up the bronze and iron essence and burned.

The high temperature inside the melting furnace is frightening, reaching several thousand degrees, but there is only a slight heat outside the melting furnace. The wall outside the melting furnace is only slightly warm and not hot at all. This is the second function of the melting furnace. These magical functions come from various inscriptions with unpredictable power.

The temperature in the furnace is getting higher and higher. Twenty minutes later, the bronze iron essence gradually begins to melt. After a while, it will completely melt into liquid. Luoyu also slowly reduces the temperature of the flame in the furnace and keeps it at a constant temperature.

&"Very good. Now heat up slowly. Remember, heat up slowly. When the impurities are found to be burned and evaporated, keep that temperature. If the temperature rises, the refined melting liquid of Taiyuan bronze iron will be burned."; Haolao said

Luo Yu did what haolao said, and gradually raised the temperature of Leiyan beast fire. When the temperature rose to a certain level, the melting liquid of bronze iron essence emitted a trace of black smoke, which were the impurities contained in bronze iron essence. At this time, Luo Yu also kept the temperature at this level.

The impurities in the molten bronze were burned and evaporated, and the volume of the molten bronze was also slowly decreasing. After half an hour, the refined molten bronze iron was one-third of its original volume in an instant.

&"It's almost done. Cool down, then turn off the engine, and then melt it. The material will be discarded.".

Luo Yu slowly lowered the temperature of the flame, and then took back the Leiyan beast fire. After the bronze melt cooled down, it slowly solidified into an irregular red iron block.

Old Hao waved, and the bronze iron essence was taken out by a force.

&"Well, it's true that 80% of the impurities were removed in the first melting and refining. You really have the talent of a caster & quot; Hao said with a smile.

&"Haha, it's all the master's good command." Luo Yu, with a smile, dare not be proud.

&"OK, now let's start the second step, forging. As it's just to make a pure bronze sword, there's no need to melt other materials & quot;

Hao took out a black forging iron table, a forging hammer and an iron clip. The hammer is not Hao's Amethyst hammer. The Amethyst hammer is too heavy for Luo Yu to wield for a long time.

&"You first fold and forge the bronze iron essence continuously. When the times of folding and forging reach 100 times, the bronze iron essence will also reach the hardness level of inferior weapons & quot; said Hao.

Luo Yu nodded, clamped the red bronze iron essence on the forging table, held the iron clamp in his left hand, and kept beating with his right hand.

Dong Dong Dong Dong!

After being flattened, the bronze iron essence was folded into two layers and continued to forge. The sound of beating was heard all the time and reverberated in the training room. While Luo Yu kept beating, his face began to sweat. The casting was also an individual work. After half an hour of beating, Luo Yu's arms were numb.

&"Strike while the iron is hot, don't stop. It's harder to forge when it's completely cold.".

Luo Yu gritted his teeth and hammered for half an hour, and finally folded and hammered repeatedly for a hundred times.

&"Well, you don't need to fold and forge. You can directly tap the long bar, and then slowly forge it into a bronze sword. &Quot;

Luo Yu picked up the forging hammer again and kept beating, and a ball of bronze iron essence was slowly forged into a strip. Because it was the first forging, the long sword shape was very irregular, with wide and narrow, thin and thick.Luo Yu looked at the sword, which was not like a sword, and the bronze sword, which was not like a ruler, was speechless.

“ Don't lose heart. It's very good to forge like this for the first time. The rest step is to return the sword to the furnace and quench it. Just heat the sword to make it red, and pay attention to the temperature of the water for quenching. The temperature of the quenching water for inferior weapons should not be too low, otherwise the material of the sword will collapse because of the temperature contrast. What you need to focus on now is forging technology. Here is my teacher There is a set of hammering method. You can practice it yourself, and then use it to forge & quot; old Hao comforted. Then he took out a book called "hammering method in rainy days" and threw it to Luo Yu.

&Luo Yu took the scroll and nodded.

&"Well, I'll teach you the preliminary method of refining weapons, and you'll find out the rest by yourself. I'll give you another three days as a teacher, and I'll come to see your forged sword embryo in three days."; Haolao then left with Xiaolan.

after haolao left, Luoyu opened the scroll and recorded the forging methods of all kinds of weapons on the rainy day. The forging method of sword ranked first, because the most commonly used weapons of most martial arts are sword and sword, and the weapons in the army are about one inch long and one inch strong. All the weapons such as spear, spear and halberd are the most commonly used, Luo Yu carefully studied the forging method of the sword, and it suddenly became clear in many places that the sword is thin on both sides and thick in the middle, so the drop hammer is very particular, where the force is heavy and where the drop hammer is light, we should pay attention to these things, instead of beating at random.

After watching it for a long time, Luo Yu put the bronze iron essence back into the furnace, heated it and took it out to continue forging.

The sound of Dong Dong has never stopped. The second time is much better than the first time. It's not so irregular, but it's not like a sword. Luo Yu once again put the bronze iron back to the furnace to forge again.

The sword embryo forged in the third time is much better than that in the first two times, but Luo Yu is still not satisfied,

go back, forge again, forge again & hellip;

there is no genius who can do anything and learn at once in the world, and all the existence of such powerful characters is blown out, some of them are only people who work hard like Luo Yu;

I don't know how many times it's been forged. In his hand, Luo Yu holds a three foot long bronze sword with a simple appearance. The blade has no edge and has not yet been honed. A long blood groove is carved on the sword face. The hilt can just be held by both hands, and the cross texture on it can prevent it from slipping.

&"Bronze sword embryo, finally forged out & hellip;
